Beast (Henry Philip "Hank" McCoy) is a fictional superhero appearing in American comic books published by Marvel Comics and is a founding member of the X-Men. Originally called "The Beast", the character was introduced as a mutant possessing ape-like superhuman physical strength and agility, oversize hands and feet, a genius-level intellect, and an otherwise normal appearance. Eventually being referred to simply as "Beast", Hank McCoy underwent progressive physiological transformations, permanently gaining animalistic physical characteristics. These include blue fur, both simian and feline facial features, pointed ears, fangs, and claws. Beast's physical strength and senses increased to even greater levels.

Despite Hank McCoy's inhuman appearance, he is depicted as a brilliant, well-educated man in the arts and sciences, known for his witty sense of humor. He is a world authority on biochemistry and genetics, the X-Men's medical doctor, and the science and mathematics instructor at the Xavier Institute (the X-Men's headquarters and school for young mutants). He is also a mutant political activist, campaigning against society's bigotry and discrimination against mutants. While fighting his own bestial instincts and fears of social rejection, Beast dedicates his physical and mental gifts to the creation of a better world for man and mutant.

One of the original X-Men, Beast has appeared regularly in X-Men-related comics since his debut. He has also been a member of the Avengers and Defenders.

Created by writer Stan Lee and artist/co-writer Jack Kirby, the character first appeared in X-Men #1 (September 1963). Stan Lee writes in the foreword to X-Men: The Ultimate Guide that he made Beast the most articulate, eloquent, and well-read of the X-Men to contrast with his brutish exterior. Further, the book opines that the Werner Roth-Roy Thomas team garnered admiration for their "appealing and sensitive characterizations of the original X-Men". Roth, under the alias Jay Gavin, had taken over for Kirby fully by issue #18, and Thomas was a new talent. Beast was given an individualized, colorful new costume, along with the rest of the X-Men by issue #39 in order to attract new readers. Jim Steranko's tenure, which added "exciting art", Roth returned, working with Neal Adams who blended Kirby's style with "realism, idealized beauty, and epic grandeur".

In Amazing Adventures #11 (March 1972), written by Gerry Conway, Beast underwent a radical change and mutated into his now familiar furry, blue appearance. The concept originated with Roy Thomas, an effort to make the character more visibly striking, and Beast also became more werewolf-like to capitalize on the success of Werewolf by Night.[citation needed] Over the next decade he would appear on the roster of several teams in titles ranging from The Avengers to The Defenders to X-Factor. It wasn't until 1991, in X-Factor #70/X-Men #1, that the Beast finally returned to the X-Men.

Beast cured the Legacy Virus in Uncanny X-Men #390 (2001), and in X-Treme X-Men #3 (2001) he experienced a further mutation into a feline being, first shown in the introduction to New X-Men (June, 2001), by Frank Quitely and Grant Morrison. As evidenced on the back cover of X-Treme X-Men Vol. 1, Chris Claremont, writer of that series in addition to both Uncanny X-Men (for sixteen consecutive years) and X-Factor, contributed much to the Beast's characterization. Citing Claremont as inspiration for his run on New X-Men, Morrison explains Beast as a "brilliant, witty bipolar scientist". Morrison continues, "I saw Henry McCoy as an incredibly clever, witty, cultured, well-traveled, experienced, well-read character so I brought out those parts of his personality which seemed to me to fit the profiles of the smartest and most worldly people I know – his sense of humor is dark and oblique. He's obviously quite clearly bipolar and swings between manic excitement and ghastly self-doubt. He has no dark secrets, however, and nothing to hide."[1]

Joss Whedon's Astonishing X-Men: Gifted story arc featured a "mutant cure" designed by Indian Benetech scientist Dr. Kavita Rao, and the prospect of "real" humanity arouses the interest of a heavily mutated Beast, who visits Rao only to discover that the drug is the product of illegal human experimentation on an unknown victim. The idea of a mutant cure, which had previously appeared in the 1992 animated series, was also the basis of the X-Men: The Last Stand movie plot and the series was even made into a motion comic. IGN called the arc focusing on Beast "best X-Men run in a decade" and lauded Whedon for flawless character dynamics.[2] According to BusinessWeek, Beast is listed as one of the top ten most intelligent fictional characters in American comics.[3]

Beast appeared as a regular character throughout the 2010-2013 Secret Avengers series, from issue #1 (July 2010) through its final issue #37 (March 2013).

Henry Philip "Hank" McCoy was born in Dundee, Illinois, in the United States, to Norton and Edna McCoy. His father, Norton McCoy, is employed at a local nuclear power plant before Henry's birth and was once exposed to intense nuclear radiation, which appears to have caused his son's mutation. Hank is born with a vast intellect, unusually long arms and legs, and unusually large hands and feet - a rare although not unique case of mutant powers manifesting before puberty.[4] His bodily proportions are comparable to those of a gorilla and later stories reveal his nickname in school was "Magilla Gorilla".

Henry's mutation more fully manifests during adolescence, providing greater strength and agility, and although his powers allow him to briefly excel in athletics during his remaining time at school, he soon attracts the animosity of his fellow students and other non-mutant humans. As he seeks refuge, he is approached by Professor Charles Xavier, who invites him to study at Xavier's School for Gifted Youngsters.

Henry recognizes the opportunities such an institution can offer him and accepts the invitation. He finds the school both a fountain of scientific knowledge and a place of sanctuary. There he is introduced to the X-Men, who accept him into their ranks and give him the codename Beast. Alongside workouts in the Danger Room, under Xavier's tutelage, he studies subjects ranging from differential equations to Proust.

With the rest of the X-Men on their first field mission, he battles Magneto for the first time,[5] and later Magneto's Brotherhood of Evil Mutants.[6] He became stressed because he had to keep a secret identity while in the X-Men team, so he briefly left the team to become a professional wrestler. While he was a professional wrestler he met Unus the Untouchable and helped him build a ray gun to make Unus completely invincible.[7] Beast then rejoined the X-Men team. With the team, he also visits the Savage Land, and meets Ka-Zar.[8] Hank even battles the Juggernaut but is badly hurt.[9] He then fights the Sentinels with the X-Men.[10] In addition, he and Iceman fight the Maha Yogi.[11] Hank later recounts his clash with the Conquistador and how he joined the X-Men.[12]

Hank leaves the X-Men shortly after his twentieth birthday, after remarking that he is no longer one of the "strangest teens of all". He becomes a research scientist at the Brand Corporation, a genetics research facility. His assistant, Linda Donaldson, quickly becomes his girlfriend. Hank isolates a "hormonal extract" allowing anyone to become a mutant for a short period of time, and uses the mutagenic serum on himself to disguise his appearance while foiling an attempt to steal his research.[13] He waits too long to reverse the process, leaving him permanently transformed. He grows grey fur, which later turns blue, all over his body and acquires pointed ears, elongated canine teeth, claws, the ability to run on walls and ceilings like a spider, enhanced senses, an accelerated healing factor, and a feral side he struggles to control. He briefly joins the Brotherhood of Evil Mutants when Mastermind wipes out his memory, but quickly recovers. When Beast is wounded, he is aided by Patsy Walker, and then reunited with his old girlfriend, Vera Cantor.[14] Back at Brand Laboratories, he discovers his girlfriend Linda Donaldson is an agent of the criminal Secret Empire, and they break up.[15]

Not long after this transformation, Beast is recruited to join the Avengers as a provisional member.[16] He is later granted full Avengers membership[17] and remains a member for many years, becoming a close friend of Wonder Man. He leaves the team periodically to rejoin the X-Men during times of need (such as The Dark Phoenix Saga[18]). Beast returns to the Avengers each time, but eventually leaves so that the team, which has a six-member limit at the time, can be filled out by new recruits.[19]

With X-Factor, Beast rejoins the original members of the X-Men, and is again reunited with Vera Cantor. Beast starts out in his furred form, but on their second mission, he is captured by Tower. He is delivered to Carl Maddicks and used in an attempt to develop a cure for mutancy, which has rendered Maddicks' son, Artie, mute. Maddicks develops a serum based on McCoy's original serum, and tests it on Beast. Hank is also subjected to chemotherapy and radiation, and suffers a cardiac arrest. X-Factor arrives on the scene and saves Hank, but not before he's been injected with the serum. When the bandages around his face are removed, he is revealed to have lost his blue fur.[24] This helps in X-Factor's cover as normal humans who are mutant hunters for hire (though they actually help the mutants they capture). When they see the need for their powers, they get new costumes similar to their old X-Men costumes, and call themselves the X-Terminators, posing as renegade mutants. Beast wears a mask as he did originally, since he now looks human again.

Eventually X-Factor clashes with the ancient mutant Apocalypse[25] after Angel loses his wings in a battle and shortly after goes missing. Apocalypse turns Angel into Death, the most powerful of his four Horsemen of Apocalypse. During the battle, Beast is touched by the Horseman Pestilence, whose touch usually causes incredible pain and viral infection. The infection interacts with the recent serum treatment of Maddicks, and instead of killing him, Hank is affected in such a way that every time he uses his superhuman strength, his intelligence decreases.[26] Though the battle is won, it comes at the cost of Hank's decreasing intelligence and Angel's humanity, which would not return for a time. Hank’s condition worsens for weeks. He even openly talks to Trish Tilby, a reporter, not realizing she might use the information on TV. Out of respect for Hank's situation, Trish does not mention his name when she reports about X-Factor’s recent battles, only that one of them lost his intellect while heroically defending New York. Beast is still hurt by her using the information at all, but she is able to convince him that she meant well.

X-Factor finally ends their charade and are hailed as heroes, and they then don costumes similar to their previous X-Terminator costumes. When Hank’s mind is nothing more than that of a child, he intercepts a mutant called Infectia who is trying to kiss Iceman. Infectia has the ability to manipulate molecular structures through touch, creating mutated "monsters". When she kisses Beast, he becomes feverish and begins switching back and forth between his normal and furred forms.[27] Finally, he stabilizes in his furry appearance, keeps his intelligence, and has more strength than ever.[28]

Hank soon resumes wearing his old costume, but now no longer has need for a mask. During the events of Inferno, Beast, along with the rest of X-Factor team up with the X-Men and various other heroes to fight the evil forces invading the city; eventually, they manage to stop a portal between Limbo and Earth from remaining open and peace returns for the survivors.[29] Soon after Inferno ends, the X-Tinction Agenda takes place where Genosha wants to punish various mutants for war crimes on their island. Here, Beast plays yet another key role. Shortly after the crisis ends, X-Factor switches costumes once more; Cyclops, Jean, and Iceman all wear identical costumes, while Beast returns to wearing trunks, and Archangel sticks to his old costume he received from Apocalypse.[30]

Towards the end of X-Factor's career, they battle the Shadow King during the Muir Island Saga. The final battle leaves Professor Xavier crippled again, which results in X-Factor rejoining the X-Men.[31]

One of Beast's greatest challenges emerges with Stryfe's fatal Legacy Virus. Hank is already despondent, as he is turning thirty and questions his life accomplishments. His frustrations are further compounded when Professor Xavier and Moira MacTaggert don't ask for his assistance with the Legacy research, but it turns out Xavier is just giving him his privacy. Perusing their data, Hank learns the problem is more difficult than he had initially imagined. Hank has always believed that, given time, he could solve any problem; the Legacy Virus becomes his obsession. He goes as far as making an unethical decision in giving Mister Sinister information on the virus, since he has more resources and fewer morals to inhibit him.[volume & issue needed]

A turning point comes when Dark Beast finishes some of the formula, occasionally prying more information from Hank whom he imprisoned and replaces for a while.[32] The most critical step toward a solution (other than when Beast individually finds the cure without acknowledgement) comes when Dr. MacTaggert discovers Mystique's irresponsible manipulation of virus strains. The cure is incomplete and it takes Beast to design the final cure. Based on Moira's notes, Beast concocts the anti-virus to much elation, but it soon is repaid with a heavy toll—Colossus chooses to sacrifice his life to release the remedy.[33]

After mourning the loss of a teammate, Hank briefly leaves the school with Storm and her X-Treme X-Men team in search of Destiny's diaries. After an attack by Vargas that leaves Psylocke dead, Beast is gravely injured and returns to the Institute.

As the world experiences a mutant baby boom, much of the mutant community seemingly begins experiencing "secondary mutations", often taking the form of additional or enhanced abilities. In the aftermath of Vargas' attack, Beast's secondary mutation is "jumpstarted" due to the powers of teammate Sage. The further mutation causes Beast to develop a more feline physique, to which he initially has some trouble adapting. A psychic attack by the genocidal Cassandra Nova leaves Beast humiliated, badly beaten (by the controlled body of his friend Beak) and haunted by the possibility that his new form is simply a step in a continuous state of devolution. Additionally, the alteration in form causes his long-time girlfriend, Trish Tilby, to break up with him after being accused of bestiality in the media. Over time, Beast strikes up a strong friendship with Emma Frost, in one incident bringing her flowers to cheer her up. He finds her diamond form shattered into thousands of pieces and spends some time putting her back together. With a final jolt of psionic energy from Jean Grey, Frost returns to life.[volume & issue needed]

Beast later uncovers what seems to be a female mutant with feline features, like his situation. This raises hopes for him, until he discovers it's not a mutant human that looks like a cat, it's a mutant cat who looks like a human. Either way, the creature is at the limit of her life and Beast allows her to leave the X-Mansion to pass away quietly in a spot she finds comfortable.[volume & issue needed]

When news of a "cure" that would reverse mutations suddenly arises, Beast finds himself seriously considering taking it so he can once again appear human. Hank eventually decides against it after vigorous "urging" by fellow team member Wolverine, as it would send out a negative message to other mutants if an X-Man were to take the cure. After learning that the cure was developed by fellow geneticist Kavita Rao through experimentation on mutant corpses – as well as on the X-Man Colossus – Beast helps take down Rao's operation. When the villainous Hellfire Club attacks the X-Men, Cassandra Nova telepathically strips away Beast's higher human consciousness, leaving him with only his animal instincts. After hunting Wolverine around campus (and even eating his leg), a student named Blindfold faces him down with a device he and Xavier had built in case his consciousness was ever lost. The device is a high-powered sensory stimulant in the form of a ball of string, which Beast had alluded to as being his greatest fear. Once restored, he is quick to put on a suit and tie and help Wolverine with a hyper-magnetic device. He, along with his teammates, are taken from the Mansion by the government agency S.W.O.R.D. and airlifted to the alien Breakworld.[volume & issue needed]

When a Civil War breaks out among Marvel's superheroes, Beast, along with the other X-Men, assumes a neutral stance. Beast was not a particular fan of the policy and secretly violates his stance by providing Spider-Man with a holographic disguise to enable him to continue teaching at Midtown High after his secret identity has been exposed.[34] Despite his personal feelings about the Superhuman Registration Act, Beast enlists his services to the Initiative program after the war's end, to assist in the training of the next generation of superheroes.[35]

The X-Men and various other mutants attend the funeral of a young mutant boy named Matt Landru who has been killed in a road traffic accident and muse on what this means for mutant-kind. Beast plans to find a way to reverse M-Day. Despite the 'aid' of his other self (the Dark Beast), along with exploring such diverse avenues of investigation as analysis of alternate timelines or an attempt to track down the Scarlet Witch, he is unsuccessful in his research, but the final part shows him holding a child wearing a three-eyed smiley face shirt saying "Evolution" on it as a promotion of the Messiah Complex.[volume & issue needed]

Beast is shown helping Professor X repair Cerebro when the X-Men are tracking down the child with the X-Gene.[36] Beast is later seen at the Mansion when it is attacked by the Sentinels, who have been taken over by an unknown person.[37] When Iceman arrives at the school with the New X-Men, Beast works with Prodigy and is able to stabilize the mortally wounded Hellion, as well as the other New X-Men and X-Men injured in their battles with the Purifiers and the Marauders, respectively.[38] He is later present during the battle on Muir Island and is among the first to reach Professor Xavier after he is accidentally shot by Bishop. Xavier's body soon disappears.[39]

In the aftermath, Cyclops has sent Beast to search for Professor Xavier, whose status is unknown by the X-Men. Beast is also seen closing down the ruins of the X-Mansion and taking Martha Johansson with him.[40]

Beast is seen as part of the team setting up a new X-Men headquarters in San Francisco, California. He is working closely with Cyclops, Emma Frost, and the rookie X-Man, Armor. He is also still seeing Abigail Brand, who requests that he take a weekend off from the X-Men so that she can 'tamper with him extensively'.[citation needed] He helps Tabitha Smith, teaching the young and flippant woman to use research instead of brutal strength to fight her enemy, a mutant with sedation powers called Nuwa.[41] He and Warren go to Buenos Aires to recruit Doctor Nemesis to help the X-Men save the Mutant race. Only after they stop tube-grown super Nazis, does Nemesis agree.[42] They also recruit Madison Jeffries.[43] Together, they created a time travel device so that they could travel into the future and retrieve the mutant Messiah. However, because they created a device for time travel in so little time, the side-effect of the device is that the user's biology breaks down upon entering the future, so it will automatically bring the person back in thirty-two and a half hours.[44]

Beast discovers that the Super-Skrulls with X-Men abilities can be infected with the Legacy Virus.[45] Despite his ethical protests to the contrary, Cyclops decides to use it on them, offering the antidote in return for the Skrulls' retreat.[46]

In order to save mutantkind from the effects of M-Day, Beast and Angel had to gather a team of specialists to help them. They gathered Madison Jeffries, Yuriko Takiguchi, and Dr. Nemesis. They then returned to Graymalkin Industries to meet their final member Dr. Kavita Rao (who was formerly trying to cure mutation). Beast and the X-Club traveled back to 1906 in order to find Dr. Nemesis' parents and discover the origins of modern mutation. During the mission, they also fought an early version of a Sentinel created by the Hellfire Club, and inadvertently caused the San Francisco earthquake. When they returned to the present, they found that their DNA evidence had been buried beneath where the Dreaming Celestial was standing in the park.[47]

After being captured, Beast became a test subject for the Omega Machine (designed by Dark Beast to eradicate mutant powers and place them in Weapon Omega) while being held prisoner on Alcatraz Island by Norman Osborn, along with Professor X.[48] Beast is shown getting weaker and mentions losing his claws while hooked up to the machine. Beast was rescued by the X-Men, and later recuperated from his injuries. Later, he spoke at the funeral of Yuriko Takiguchi when Magneto had arrived.[49] Beast seemed increasingly disillusioned with Cyclops' leadership and methods, such as allowing Magneto to become a member to his time under torture under the Dark Beast.[50] This resulted in Beast leaving the X-Men.[51]

After leaving the X-Men, Beast opted to join his current girlfriend Agent Abigail Brand as a member of S.W.O.R.D.[volume & issue needed] However, shortly after joining her in space, Brand's co-commander, Henry Peter Gyrich (hired by Norman Osborn) begins to round-up the aliens residing on Earth, in a xenophobic attempt at avoiding another Secret Invasion.[volume & issue needed] As a result of Henry's plan, he has even made moves against Brand, resulting in her, Beast, and the dragon Lockheed, becoming fugitives from S.W.O.R.D. and attempting to overthrow Gyrich.[volume & issue needed][52]

Beast later returns in an issue of Uncanny X-Men to attend the funeral of his friend and teammate, Kurt Wagner (Nightcrawler) where he confronts Scott Summers and blames Kurt's death on Scott's increasingly militant and extremist attitude to protecting the mutant species at all costs (even at the cost of sacrificing his friends to do so).[53] Despite his issues with Cyclops, Beast remains on Utopia to help deal with the attacks being made by Bastion.[volume & issue needed] Following Bastion's defeat at the hands of Hope Summers, Henry again departs Utopia.[volume & issue needed]

After the separation of the X-Men into two teams, Beast is in the team that goes with Wolverine to open The Jean Grey School for Higher Learning in Westchester County, New York.[55]

During the Avengers vs. X-Men miniseries, Beast sides with the Avengers to investigate and stop the Phoenix Force's return to Earth.[volume & issue needed] Hank joins the team of Avengers sent to halt the Phoenix Force's return to Earth,[56] but later temporarily resigns from the Avengers in protest against their efforts to stop the 'Phoenix Five'- the five X-Men who have received the power of the Phoenix Force – as their actions appear to initially be benevolent.[57] He returns to aid the Avengers and the X-Men when Cyclops and Emma Frost begin to be corrupted by the Phoenix's power.[58]

In the aftermath of the Phoenix War, Cyclops now actively strikes out at government organizations and holds mutants prisoner, with the X-Men unwilling to actively fight him as they fear the subsequent mutant civil war that might result. Beast, who is apparently dying due to side-effects of his secondary artificially-accelerated mutation, stumbles upon a solution after a chance comment from Iceman who says "the past Cyclops wouldn't tolerate his present self's actions". Beast travels back in time to the early days of the Xavier Institute to bring the original five X-Men from that period into the future, hoping that Scott's past self will be able to convince his present self to stand down.[59]

Beast lapses into a coma shortly after bringing the team into the present,[60] and Jean's telepathy, which is artificially accelerated by the trauma of her trip to the future and witnessing what Scott has become,[61] manages to connect the minds of the two Hanks. This allows the younger Hank to spot a mistake in his future self's calculations and stabilize his physiology by reverting to a blue furred ape-like state again, though this time, his ape-form is bald and has no head hair aside from the blue fur covering his whole body.[62] The young X-Men decide to stay in the present and become the All-New X-Men, except for Angel who joins Cyclops' Uncanny X-Men.[volume & issue needed]

After Cyclops goes to Muire Island and discovers that all of the mutants died painful deaths, he calls Beast to do a diagnosis and Beast discovers that somehow that the Terrigen cloud, the substance that gives Inhumans their powers, has become toxic towards mutants after mixing with the atmosphere changed its structure.[63] Hoping to bridge Inhuman and Mutant relations in light of this new conflict, Beast works with the Inhumans to find a way to make the Terrigen cloud safe for mutants while making sure it remains suitable for Inhuman powers. He becomes a trusted ally to the Inhumans and joins their counsel.[64]

When the present Beast realizes that he cannot find a cure for the Terrigen cloud, he visits the rest of the mutants and advises them that the best course of action is for all mutants to leave Earth, but his teammates object and imprison him before he can warn the Inhumans that war is coming.[65] However, after learning what the cloud will do to mutants, Medusa activates a generator to destroy the Terrigen cloud, leaving Emma to be branded a traitor for her false claims inform about Cyclops' true death to manipulate the X-Men into destroying the Inhumans. Havok helps Emma to escape for the sake of his brother's memory, while Beast and his remaining teammates make up, all regretting what their lives have come to ever since discovering that the Terrigen could kill them.[66]

Following the reconstruction of reality after the Battleworld crisis, the displaced X-Men remain in the future, travelling the world as they try to find their place, while the 'present' Beast works with the Inhumans to find a means of resolving the recent release of Terrigenesis crystals that have proven dangerous to mutants.[volume & issue needed] Increasingly frustrated with his inability to find a way back to their time through science, the young Beast contacts Doctor Strange for advice on using magic, but although Strange cannot help due to his currently weakened powers, when Hank is able to help him find a solution to a dimensional rift he was investigating, Strange reassures Hank that he is smart enough to find a solution to the current dilemma.[67] After the conflict with the Inhumans is concluded, the younger Beast reveals to his teammates that he has determined, through a combination of science and magic, that the younger X-Men cannot return to the past as they are already there, leaving them free to travel the world and find their own place.[68][69]

The young Beast finds himself working alongside Magneto along with the rest of the time-displaced X-Men doing whatever it takes to preserve Xavier's dream. Beast begins to use magic more freely on their missions, something that greatly distresses Cyclops. Whenever they're at X-Men HQ Beast spends most of his time on his own to continue study magic and becomes increasingly reclusive in the process.[70]

It is possible that Beast's mutation is a result of genetic atavism.[71] However, he also possesses neotenous characteristics, which may explain him having a genius-level intellect despite his animal physique.[71] He also possesses superhuman strength, speed and agility. He is an excellent hand-to-hand combatant, employing a unique style of acrobatic combat, from combat training he received at Professor Xavier's and coaching from Captain America.

Originally, Hank McCoy retains the basic features of a normal human alongside a generally simian physiology (e.g., elongated limbs and enlarged extremities) equivalent to that of a Great Ape. This mutation gives him superhuman strength, speed, reflexes, agility, flexibility, dexterity, coordination, balance, and endurance. Hank is equally dexterous with all four limbs; able to perform tasks with his feet or hands with equal ease. Because of his talents and training, Beast can outperform any Olympic-level athlete, contorting his body and performing aerial feats gracefully. His strength and dexterity allow him to climb vertical surfaces with just his hands and/or feet,[72] jump great distances[7] and survive falls that would kill any ordinary person.[73] He also possesses enhanced senses and can track people for great distances over open terrain[8] and his feet are sensitive enough to detect electronic signals (from bombs, listening devices, etc.) through solid walls and floors.[74] Later, he drank an experimental solution of his own making and mutated further through the growth of grey fur covering his entire body and the enhancement of all of his existing abilities, especially his strength, and Hank also gained a nearly instantaneous healing factor.[75] The psychological impact of this first transformation caused Beast to experience short-term amnesia and also made it difficult for him to control his animalistic instincts, which would cause him to slip into an uncontrollable berserker rage during combat.[76] However, his body suddenly mutated again after a short time, changing his fur color from grey to black (although comic book printing technology depicted it as blue), returning his strength back to previous levels, and losing his healing factor.[14] He was also able to more easily control his animal instincts after this second mutation. Beast gained the ability to emit mood altering pheromones, causing sexual attraction in women.[citation needed] During this time he was occasionally depicted with claws and fangs, but these were not a part of his original mutation.[14] Hank McCoy briefly returned to his humanoid/simian form[77] with his hair color now being depicted as black, not reddish brown. However, as a result of being touched by Pestilence his strength began to increase exponentially while his intellect began to decrease.[78]

After Infectia's kiss restored Hank to his simian physique, his intellect had stabilized and returned to his previous genius-level, and his strength had increased to superhuman proportions.[79] Beast's fangs and claws became a consistent part of his appearance after this return to his "blue and furry" form.

After being critically wounded,[80] Hank's body undergoes a secondary mutation, jump started by Sage. The result is a more feline appearance equivalent to that of a big cat. His strength, speed, stamina, sturdiness, and senses increase further with this change. He gains cat-like agility, flexibility, coordination, and balance, and all his senses are enhanced to twenty times that of a normal human being. In addition, Beast develops an accelerated healing factor that allows him to repair mild to moderate injuries within the span of a few hours. However, as his hands and feet change from simian to feline (going from a normal human set of four fingers to just three, retaining the opposable thumb), he loses his superhuman dexterity, once admitting that he used to play the guitar, but is now learning to play the drums instead. Following the X-Men's relocation to San Francisco, Beast discovers that he had regained some of his old manual dexterity. In the first issue of Warren Ellis' Astonishing X-Men run, Beast also comments he no longer needs full sleep.[volume & issue needed]

It is later discovered that his secondary feline mutation is still detrimental to his health: as such, with the combined efforts of past versions of Jean Grey and himself, Beast's condition was stabilized in a more human-like form, possessing blue fur and larger than the average human male but otherwise fairly human.[62]

After a meeting with Doctor Strange, the displaced younger Beast has mastered a combination of science and magic, allowing him to return himself and his four teammates to the past for a few minutes, although he notes that it took a great deal of effort to send them back for that long and it merely confirmed that history has been 'reset' so that the displaced X-Men are no longer 'needed' in the past.[68] He has also mastered a mystical portal that allowed him to send the Juggernaut to Siberia after passing through Hell.[83]

According to writer Will Murray, a possible inspiration for the Beast was Andrew Blodgett "Monk" Mayfair, a companion of pulp hero Doc Savage. Both are possessed of an apelike appearance and are brilliant scientists. Before becoming more erudite in later issues, McCoy also used a great deal of slang in his early appearances much like Monk.[84]

The ape-like Beast appears, alongside the other original X-Men, in the episode "The Origin of Iceman" of the 1981 animated series Spider-Man and His Amazing Friends. He is seen in a flashback in his original form and has no lines.

Beast is a regular character and member of the X-Men in the 1992 X-Men animated series, voiced by George Buza. He appears in his blue simian form throughout the entire series.

Buza also voiced Beast in the two-part episode "The Mutant Agenda"/"Mutant's Revenge" of the Spider-Man animated series, a crossover with the 1992 X-Men series.

Beast appears as a regular character beginning in the second season of the 2000 animated series X-Men: Evolution, voiced by Michael Kopsa. He starts off as the chemistry and gym teacher of the high school the younger X-Men attend, suppressing his mutation through a serum he developed. Eventually the serum starts to fail, and he mutates into the furry blue "Beast" and joins the X-Men.

Beast is again featured as a regular character in the 2009 animated series Wolverine and the X-Men, voiced by Fred Tatasciore. He is the first X-Man recruited by Wolverine in the series, being the only X-Man to have stayed behind after the destruction of the X-Mansion and the disappearances of Professor X and Jean Grey.

Beast appears in Marvel Anime: X-Men, voiced by Hideyuki Tanaka in the Japanese version and by Fred Tatasciore in the English dub. This version of Beast is shown in his cat-like appearance.

Beast was included in early drafts for the 2000 film X-Men, but had to be removed for the film to be greenlit by the studio, due to budget concerns.[85] Elements of his persona, including his medical expertise and political activism, were transferred into Jean Grey's character.

Steve Bacic makes a brief cameo as Dr. Hank McCoy in the 2003 film X2, on a television screen in a bar.

Nicholas Hoult portrays a younger Beast in the 2011 prequel film X-Men: First Class.[86] Actor Benjamin Walker was originally cast in the role, but dropped out of the film to star in the Broadway musical Bloody Bloody Andrew Jackson.[87] McCoy's most notable character facet in the franchise from this point on is his long-lasting crush on Mystique. In the film, he originally possesses only prehensile feet and enhanced speed, agility and reflexes. He attempts to cure himself of his mutation with a serum derived from Mystique's DNA, but this causes his transformation into his familiar blue-furred feline form.

Hoult and Grammer returned as Beast in the 2014 film X-Men: Days of Future Past.[88] Hoult revealed to Joblo that Hank created a serum which controls his mutation, making him appear human unless he gets angry.[89] Grammer reprised his role as the older Beast in a cameo at the end of the film.[90] When asked by the younger Beast if he is alive in the future, Wolverine tells him that he is not. A viral marketing website for the film shows that Beast was killed in 2015 by an angry mob of human protesters outside his home in upstate New York.[91] Wolverine's actions in the past – during which he interacted with the younger Beast and warned him and Xavier about the future – create a new timeline where Beast is alive, with Wolverine seeing the older Beast (an uncredited Kelsey Grammer) walking through the Xavier Mansion when he returns to the future.

Hoult reprised his role as Beast for the final time in X-Men: Apocalypse.[92][93] Still using his serum to maintain his human form, Hank has also developed a new jet in the mansion's basement, respecting Xavier's dream to make the mansion a full university for mutants and humans but preparing for war nevertheless. He reverts to his "beast" form after the mansion is destroyed in the first confrontation with Apocalypse when he is captured by Stryker and thus misses his shot, but subsequently pilots a jet stolen from Stryker's own fleet to Cairo to confront Apocalypse, engaging the Horseman Psylocke in battle, with her telekinetic-enhanced leaps and her mental sword matched by his greater physical strength and reflexes. At the film's conclusion, Beast is depicted as one of Xavier's lieutenants (along with Mystique) with the revived X-Men team.

In the Marvel magazine, Marvel Vision, for most of the series Beast was the supposed author of his self-titled "Beast Files". This series of 2-page articles was perhaps the first time a character in any comic universe was depicted to be keeping detailed profiles on other heroes and villains.[citation needed] This format has been adopted since by many other books, including most notably the Alex Ross series, Justice (DC Comics) which had 2 profiles in each issue during the mini-series' 12 issue run. The files appeared for over 2 years, and the column was voted the fan-favorite.[citation needed] "Beast Files" was actually written by Benny R. Powell.[citation needed]

Beast has received positive reception as a comic book character and a member of the X-Men. Wizard magazine ranked Beast the 180th greatest comic book character of all time, on their list of the Top 200 Comic Book Characters of All Time.[100]IGN ranked Beast as the 58th greatest comic book hero of all time stating that Beast embodies everything about the mutant struggle in the Marvel Universe.[101]IGN also ranked Beast as the 9th greatest X-Men member stating that when the world can accept Henry McCoy, the X-Men will have succeeded in their mission,[102] as #7 in their list of "The Top 50 Avengers" in 2012.[103]
